T o all "trimm it 'may concern: Y

Bc itlinown that, I, ALFRED ALLEN, a citizen of the ['nited tutes, :md aresident; of Oakland, in the county of Alameda and Stute of California,have. invented new and useful improvements in Wave-Motors, of which thefollowingr is n specification.

This invention relates to improvements made in apparatus or devices frconverting the power of the waves into rotary motion of a shaft. tooperate nmchinery, eompref-s air, und perform other useful work.Apparatus for this purpose :ire generali) embraced nnder the title ofWave-motor.

The ohjeet of the invention` is the production of :in improvedwnvcanotor, in which the comhined motions of n floating hull or bod` :isprodneed hy t-lic waves :md the angular movements of pivoted hooms orlevers on the hull orV hodv and oscilluted hv the. Waves, are utilized:md caused lo give rotanv motion of n shaft on the hull, ond from whichby Suitable meelmnir'nl means power can ho transmitted or applied to douseful Work.

To sueh end und ohjeet, chiefly, my invention eomprises :t novelconstruction und comhinntiou of hull or imdv, oseilluting hooms, orlevers pivotnllv mounted on the indi, und means for convertingr themovements ci' the Looms or levers into rotnry'molion of u shaft. f

shaft of an air-compressing machine to the .r D ne? that the dogs ontheir ends will engage the teeth of the two eogwheels n-n,and the tirowheels are in turn gea red into u common shaft t through the medium ofpinions e-r on the axes s-fs, and a spur-wheel w on the shaft t.

The pfuvls p-pl of each boom are held in Workin;- contaet with theircoe-wheel by aneighted arm y placed on the opposite. side of the pivotof each dog. As-these working' arts are submerged when in operation,however, the means connecting the booms with the cogwheels should be oia strong,r and simple construction and with the View to In the mechanismherein employed, the pan'ls p--p are so situated on opposite sidesolthel pivotal point of the boom that. one pawl wil catch and act on thewheel when t ie outer end of the boom is ascending. or is thrown a hovetbe lmrizontal; whereas, the other pawl will act in the descendingmovement, with the eil'ect to produce a continuous movement, of thewheel in the same direct-ion on its axis.

The shalt. t to which tbe movements of the wheels 'fz-n are transmittedto produce natal-5 motion, is Situated amidship, and the hull is sobalanced or ballasled that. the loud will be equally distributed onopposite sides of the center of the hull, thereby securing-an evenrocking or milling motion of thc hull in a fore and aft direction.

The pivotal points of the booms are situated also on opposite sides ol,and equidistant fron'. the center, and the length of the booms from thepivotal mint; to the ilnat on the outer end should he calculated withtbe view to 'reduce an even oscilla tion or, movement. of t ie hull onboth sides of the The shaft t is eoluiccted with or into the wheelsvn---n by means of spur-gears and pinions, as shown.

It m'll be evident that the motion imparted to the shaft tmay betransmitted or various ivell-knmvn mechanical means, to operatemachinery, and do other work, as, for example, by lixing a sheave z onthe shaft t to earr) an endless wire cable, as illustrated in Fig. 3; orby connecting the Ashaft t. and by that means compressingr air in a tankby the power taken from the shaft.

The hull is controlled and maintained in proper worliingg,r positionwith reference. to the currents and the direction of the waves h vanchors and cables, usually attached to the forward boom; but attachedas well at other points or parts of the apparatus where they will bel'ound best adapted to maintain 6e the hull and the booms end 011 to thewaves and currents.

The apparatus above described consisting of a hull dividedlongitlulinallv bv central wells. or compartments npeningthrough the ufbottoni, and two longitudinallyv extending e side b v 'shalt extendingacross or through the hulls.

booms, is the simplest form in which I have embodied myinvention.- Itshould be 1neutioned, however, that the number ol booms ma) be increasedand the hull be constructed with a greater number of openings` for thebooms to work in; or a series or number ot hulls of the constructionillustrated in Figs. 1 and 5 may be coupled or connected together sideto act on or operate a common In the modification which is illustratedin Figs. 6 and 7 the levers are arranged in pairs or couples on opposite`sides et the hull, with those ol` the same pair extending fore and uitfrom the same pivotal point, so as to swing in opoosite arcs thercl'rom.

lhe shorter le verf1 ol' each pair is lieved on tbe outer end of a solidrock-shaft 2 on tbe inner end of which is lived the head 4 carrying thepawls 5 6. The longer lever f/l of each pair is fastened on the outerend ot'a tubular shaft J3, that has a similar head 'i carrying,T poulsS-l secured on the in ner end. as seen in Fig. 'l'he two sets of pawls5-6, 8 9 aro under and in line with tivo toothed- Wheels 1012, thataremourned on and connected to a common shaft lb by clutches of anywell-known construction, so that each toothed wheel being actuated byits own lever and pan'lsmay act separatel) on the shaltl 13 torotate thesame without uuduestrain or tension on the shaft.

The motion of the shaft 13 is transmitted by-gears and pinions 14--1-5,14x-15X to a shaft 16 carrying a sheave 17 for a transmitting.r cable orchain-belt.

Having thus described my invention, what I claim and desire to secure bLetters Patent is:-
